Available in PDF, EPUB and Kindle. Book excerpt: Almost twenty years ago DE DuvE discovered the existence in rat liver cells of a novel class of subcellular structures which he termed lysosomes. As the lysosomes are the seat of various hydrolytic enzymes this discovery greatly stimulated the interest in cellular digestive processes. It is now recognized that compartmentation of hydrolases is an outstanding example of the dependence of metabolic functions on cell structure. The important role of lytic processes in plant metabolism made it interesting to correlate the facts on the various phenomena and present them from the point of view of cellular compartmentation. It is not intended to survey in extenso the litera ture on the various aspects of localization and function of hydrolases in plant cells as this would be an impossible task. The aim of this monograph is to emphasize the significance of hydrolase compartmentation rather than to strive for complete coverage of work on hydrolases in which other viewpoints have been considered. I thank Miss SONIA TURLER for her great help with the manuscript. I also wish to acknowledge the assistance given by Dr. ELSA HAUSERMANN, Mrs. DORLI FURRER, and Mrs. SILVIA STUNZI. Moreover, I am indebted to my collaborators and particularly to my colleague Dr. A. WIEMKEN for frequent and stimulating discussions on the subject. Zurich (Switzerland), February 1975 PH.

Book Synopsis Vacuolar Compartments by : David G. Robinson
Download or read book Vacuolar Compartments written by David G. Robinson and published by CRC PressI Llc. This book was released on 2000 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research into plant vacuoles has, over the last 5 years, been injected with new data which have already radically changed our concept of the vacuolar compartment in plant cells. In fact, we should no longer speak of the vacuole, but rather of vacuolar compartments. This is a revolutionary change in the way in which the plant cell has traditionally been presented in the biological literature. Vacuolar Compartments is a timely volume that provides a broad overview of our current understanding of the roles of vacuolar compartments in plant cells. Chapters focus on individual function of plant vacuoles and the tonoplast machinery that supports them. Additional chapters present up-to-date information on the identity of different vacuole types and the traffic of proteins to them. The book also provides a basis for comparing the plant system to vacuoles in other organisms. The present challenge is to understand how the separate organelles in the system are generated and maintained by the cell, and to explain at a biochemical level the functions of each vacuole type and the mechanisms by which they are achieved. Vacuolar Compartments is the first book to provide this perspective.
Book Synopsis Plant Cell Biology by : William V Dashek
Download or read book Plant Cell Biology written by William V Dashek and published by Science Publishers. This book was released on 2006 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there are a few plant cell biology books that are currently available, these are expensive, methods-oriented monographs. The present volume is a textbook for "upper" undergraduate and beginning graduate students." This textbook stresses concepts and is inquiry-oriented. To this end, there is extensive use of original research literature. As we live in an era of literature explosion, one must be selective. These judgements will naturally vary with each investigator. Input was sought from colleagues in deciding the literature to include. In addition to provision of select research literature, this volume presents citations and summaries of certain laboratory methods. In this connection, the textbook stresses quantitative data to enhance the student?s analytical abilities. Thus the volume contains computer-spread sheets and references to statistical packages, e.g. Harvard Graphics and Statistica.

Book Synopsis Plant Cell Organelles by : J Pridham
Download or read book Plant Cell Organelles written by J Pridham and published by Elsevier. This book was released on 2012-12-02 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Cell Organelles contains the proceedings of the Phytochemical Group Symposium held in London on April 10-12, 1967. Contributors explore most of the ideas concerning the structure, biochemistry, and function of the nuclei, chloroplasts, mitochondria, vacuoles, and other organelles of plant cells. This book is organized into 13 chapters and begins with an overview of the enzymology of plant cell organelles and the localization of enzymes using cytochemical techniques. The text then discusses the structure of the nuclear envelope, chromosomes, and nucleolus, along with chromosome sequestration and replication. The next chapters focus on the structure and function of the mitochondria of higher plant cells, biogenesis in yeast, carbon pathways, and energy transfer function. The book also considers the chloroplast, the endoplasmic reticulum, the Golgi bodies, and the microtubules. The final chapters discuss protein synthesis in cell organelles; polysomes in plant tissues; and lysosomes and spherosomes in plant cells. This book is a valuable source of information for postgraduate workers, although much of the material could be used in undergraduate courses.
Book Synopsis Introduction to Plant Cell Development by : Jeremy Burgess
Download or read book Introduction to Plant Cell Development written by Jeremy Burgess and published by CUP Archive. This book was released on 1985-05-16 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is about plant cells and the way in which their behaviour is regulated to suit the function which they fulfil in the plant. The purpose of the book is to emphasise the structural and spatial events which occur during the development of specialised plant cells. It is designed to fill the gap between descriptive anatomy books on the one hand and purely physiological books on the other. Its novelty is in its emphasis on the interaction between the structure of a plant cell and the way in which it performs its role in the plant. It is written in two parts, of four chapters each. The first part concentrates on cells as individuals, and presents a detailed account of their structure in various situations, together with descriptions of how such structures are achieved and function. The second part places these descriptions in the context of tissues, organs and whole plants.
Book Synopsis Plant Cell Compartments--selected Topics by : Benoît Schoefs
Download or read book Plant Cell Compartments--selected Topics written by Benoît Schoefs and published by . This book was released on 2008-01-01 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membranes separate the interior medium from the exterior. Obviously, separation does not mean isolation and the membranes, as we can see them at present, act as selective filters across which different types of compounds such as salts, waste, nutriments, nucleotides, etc are transported. Depending on the molecule to be transported several ways can be used. How nucleotides are transported through the thylakoid membranes to the lumen and used in the chloroplast is the aim of the chapter by Drs. Spetea and Thuswaldner, while that of Drs. Paulilo and Falkenkrog reviews the composition of nuclear pores that mediate all the traffic between the nucleus and cytoplasm. In which ways, during evolution, the first cells were formed and how the different compartments appeared remain as tremendously exciting questions, but so far unsolved in many cases. Several theories have been proposed. The best known is that proposed by Margulis (1970), according to which an ancestral anaerobic prokaryote would become able to ingest solid particles such as other prokaryotes. In some cases the ingested bacteria continued to live and have evolved to give different types of membranes that eukaryotic cells contain today. This theory, also called the endosymbiotic theory, explains the origin of both the chloroplasts and the mitochondria, two major organelles of plant cells. More recently, another symbiotic theory has been proposed by Martin and Müller (1998) to explain the origin of mitochondria. While the contribution by Dr. Bizanz and collaborators traces back the unexpected fate of plastids in today's prokaryotic parasites of animal cells, the chapters by Drs. Solymosi and Schoefs, Dr. Chamarovsky and collaborators and, Dr. Rohacek and collaborators are dedicated to the biogenesis and functioning of the chloroplast membranes. The way of differentiation of the other organelles and cell compartments remain so far as unanswered questions. The search for analoguous compartments in lower organisms may provide the first elements of an answer. The chapter by Dr. H. Guo enters in this frame and offers a good example for the existence of a putative, so far unrevealed compartment analogue to the higher plant vacuole in cyanobacteria. The plant cell turgor is maintained thanks to the functioning of two typical compartments of plant cells i.e. the cell-wall and the vacuole, but these compartments play other important roles in plant physiology. The chapters by Dr. El Gharras and Dr. Martinez on the accumulation of betalain pigments in vacuoles and strawberry cell-wall softening, respectively, illustrate these aspects of the field. Even if plant cells are surrounded by a thick and rigid cell-wall, their interior is highly dynamic: the organelles are able to move. The contribution by Dr. Foissner analyzes the dynamic of mitochondria in Chara internodal cells. In contrast to animals, plants cannot escape from adverse conditions. Consequently, they have developed strategies to survive to biotic or/and abiotic stresses. In this book the description of the answers of plants to several stresses are the aim of some chapters. While the contribution by Dr. Ben Khaled and collaborators reports on the peroxidase activity in palm plantlets inoculated with arbuscular mycorrhiza fungi in the presence of biocontrol agents, the chapter by Dr. Dumas-Gaudot and collaborators, describes the modifications in the protein composition occuring during the differentiation of the arbuscules. The formation of the arbuscule is accompanied by a redistribution of the colonized root cell organelles around the arbuscule and by a dramatic change in the plastid metabolism allowing them to produce secondary metabolites, including secondary carotenoid and apocarotenoid molecules (chapter by Dr. Fester). Abiotic stresses, such as nitrogen deficiency, are also able to trigger the production of secondary carotenoids. Dr. Lemoine and collaborators review such a strategy in green algae. Because secondary carotenoids are usually high added value compounds, the knowledge about the functioning of the different compartments in such a production is also of great importance for the economic side of plant science s.l. How chloroplasts cope with heavy metals is discussed in the chapter by Dr. Poirier and collaborators. During the last years, new technical tools such as confocal imaging became more popular. Their use revealed the presence of new compartments, sometimes being divided into subtle sub-compartments. The intention of this book is to bring together a serie of outstanding contributions dealing with the biosynthesis, content, distribution, function, and physiology of various plant cell compartments. By combining the major contributions in this book, I wished to contribute to the propagation of the recent developments in plant cell biochemistry and physiology, to the discovery of the wonderful plant world and, also, to mutual exchange of ideas. Without the excellent work of the different authors, who have taken great care to present an up-to-date review of their field and 'Research Signpost' as the commercial editor, this book could not have been produced. I wish to dedicate this book to the different mentors in Belgium, Czech Republic and France, who showed me the scientific way and, also to my wife for her everlasting support to me.
Download or read book Plant Vacuoles written by B. Marin and published by Springer. This book was released on 1987-11-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this book, illustating the present status of knowledge related to the vacuolar compartment of fungi and plants, were presented at an Advanced Research Workshop entitled "Plant Vacuoles. Their Importance in Plant Cell Compartmentation and their Applications in Biotechnology" held in Sophia-Antipolis, France, on July 6-11, 1986. The organizers were fortunate in being able to assemble representative leaders of all the above fields of research concerning this compartment. These scientists from all over the world were invited to present their latest results and to exchange views and plans for continued research in this highly exciting field, which is very important for the improving the industrial aspect of plant biotechnology related to the production of molecules with a high added value. To ensure maximal flexibility and opportunity for dicussion, the chairmen of the various sessions were asked to introduce their respective topics, after which they were given the freedom of organizing their sessions in a more or less improvised fashion, with brief presentations of relevant new information by participants following a schedule fixed relatively shortly before the workshop. This procedure proved to be highly successful, giving rise to most productive and stimulating discussions among the representatives of the various fields.

Available in PDF, EPUB and Kindle. Book excerpt: Plant cell biology is a natural science which studies the physical structure as well as the chemical and physiological processes related to plants at the cellular level. Plant cells are eukaryotic cells which are found in the photosynthetic eukaryotes of the Plantae kingdom. Some of their distinctive features are the presence of a cellulosic cell wall, capability to store starch, presence of plastids and ability to perform photosynthesis. Plant cells and tissues can be majorly classified into parenchyma cells, collenchyma cells, sclerenchyma cells, xylem, phloem and epidermis. This book presents this complex subject in the most comprehensible and easy to understand language. It aims to shed light on some of the fundamental concepts of plant cell biology. This book will serve as a valuable source of information for those interested in this field.
Book Synopsis Plant Lipid Metabolism by : J.C. Kader
Download or read book Plant Lipid Metabolism written by J.C. Kader and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of papers that comprehensively describe the major areas of research on lipid metabolism of plants. State-of-the-art knowledge about research on fatty acid and glycerolipid biosynthesis, isoprenoid metabolism, membrane structure and organization, lipid oxidation and degradation, lipids as intracellular and extracellular messengers, lipids and environment, oil seeds and gene technology is reviewed. The different topics covered show that modern tools of plant cellular and molecular biology, as well as molecular genetics, have been recently used to characterize several key enzymes of plant lipid metabolism (in particular, desaturases, thioesterases, fatty acid synthetase) and to isolate corresponding cDNAs and genomic clones, allowing the use of genetic engineering methods to modify the composition of membranes or storage lipids. These findings open fascinating perspectives, both for establishing the roles of lipids in membrane function and intracellular signalling and for adapting the composition of seed oil to the industrial needs. This book will be a good reference source for research scientists, advanced students and industrialists wishing to follow the considerable progress made in recent years on plant lipid metabolism and to envision the new opportunities offered by genetic engineering for the development of novel oil seeds.
Book Synopsis Endocytosis in Plants by : Jozef Šamaj
Download or read book Endocytosis in Plants written by Jozef Šamaj and published by Springer Science & Business Media. This book was released on 2012-10-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocytosis is a fundamental cellular process by means of which cells internalize extracellular and plasma membrane cargos for recycling or degradation. It is important for the establishment and maintenance of cell polarity, subcellular signaling and uptake of nutrients into specialized cells, but also for plant cell interactions with pathogenic and symbiotic microbes. Endocytosis starts by vesicle formation at the plasma membrane and progresses through early and late endosomal compartments. In these endosomes cargo is sorted and it is either recycled back to the plasma membrane, or degraded in the lytic vacuole. This book presents an overview of our current knowledge of endocytosis in plants with a main focus on the key molecules undergoing and regulating endocytosis. It also provides up to date methodological approaches as well as principles of protein, structural lipid, sugar and microbe internalization in plant cells. The individual chapters describe clathrin-mediated and fluid-phase endocytosis, as well as flotillin-mediated endocytosis and internalization of microbes. The book was written for a broad spectrum of readers including students, teachers and researchers.
